If you buy a vento now, your loan is 5/7/9 @ 0.88/1.28/1.68%
3 years FREE maintenance @ 15/30/45k
5 years warranty (standard)
on the paper , rebates 10k
off the paper, simply can ask 12-15k provided on how you nego with the salesperson

Comes to review
1) driving experience surely > jap + kimchi car on the same segment , try it on vios/city/jazz/rio , the differences is incomparable, the only one come close is Mazda 2
2) interior is typical minimalist feel, if you love sporty or likes to furnish with plenty of features, this model not suits you, go for mazda2/city
3) maintenance wise you only need to think about 60/75k to fulfill its warranty unless you drive a lot then different story. Non-authorize workshop with reasonable price are plenty out there nowadays. For wear and tear parts, just get it elsewhere .
4) warranty wise still the same or improve maybe as vw started to look serious into that since last incident (i assume you know what it is)
5) if depreciation is part of your concern, just forget about it. Today you buy, tomorrow lose 30% at least
6) no keyless, no pushstart, no side mirror auto closeup etc, just an old school euro car

sekian

well , yes you are right because vento body is heavier, so it depends on your driving behavior
if you go for jazz, the close one that can compare to is polo
